Is arbitrage betting worth it?
Yes, if you treat it as a process. Once both legs are placed at the quoted odds, an arbitrage pays a profit whichever way the event goes, and small, repeatable margins add up fast with the right setup. Here are the real numbers, and a calculator to run your own.
Why it works
- The profit is locked in before the event starts, once both legs are accepted. No predictions.
- Margins of typically 2% to 5% a trade, repeated many times a month.
- Scanners find the opportunities for you across hundreds of books.
- It scales: more bankroll and more books mean more profit.
What you need
- A bankroll spread across several sportsbooks and an exchange.
- A good calculator, and a scanner once you're ready to scale.
- A simple routine: check, place both legs fast, log the trade.
- The discipline to only take real arbs, never "extra" bets.
How arbitrage makes money
When the best prices for every outcome of an event, each from a different book, add up to less than 100% implied probability, you can stake every outcome and lock in a profit. The arbitrage calculator does the split for you. Each trade typically locks in 2% to 5% of the money you stake, so the income comes from repeating trades many times a month.
That makes three things decide how much you earn: how much you stake per trade, how many trades you place, and what your tools cost.
Two scenarios, worked out
Both use an average margin of 3.5%, the middle of the 2% to 5% range, and include a scanner subscription and an allowance for the occasional mistake. Scanner prices vary: BetBurger, for example, lists €79.99 a month for pre-match and €319.99 for pre-match plus live (October 2026). We use about $90 and $350.

Scenario 2 stakes $96,000 a month from a $10,000 bankroll, so the same money is used about ten times a month. That works because most events settle within a day or two; markets that settle weeks later tie up money for longer.
The pattern is clear: the scanner is a fixed cost, so the more you stake and the more trades you place, the more of the margin you keep. A starter keeps about two thirds of the gross profit; a serious arber keeps nearly 90%. Margins vary from trade to trade, which is why each scenario shows the range from 2% to 5%.
Keep your accounts working for longer
Some sportsbooks limit customers who consistently take their best prices. Experienced arbers plan for it from day one, and it is a manageable part of the job. The full playbook is in how to arbitrage bet without getting limited; the essentials:
- Round your stakes. $500 looks like a normal bet; $493.98 looks like a calculation. Our calculator rounds for you.
- Use many books, so no single account carries all your volume.
- Add venues that don't limit winners. Betting exchanges such as Betfair and Smarkets earn commission on winnings, and prediction markets such as Kalshi let you trade against other users. See the Kalshi arbitrage guide.
- Avoid instant withdrawals after every win.

Is arbitrage betting still possible in 2026?
Yes. Sportsbooks, exchanges and prediction markets still price the same events differently, because they update at different speeds and serve different customers. Scanners track hundreds of books and flag the gaps as they appear, around news, in less-watched markets and between venues that update slowly. The arbers who do well are the ones who act on them quickly.
How to start
- Choose your bankroll and split it across several books, so you never wait for a deposit.
- Start with smaller stakes for a few weeks to build a clean, fast routine.
- Focus on margins of 2% and up. They leave room for small price moves and fees.
- Log every trade: books, odds, stakes, fees and the result. Your log shows exactly how well it works for you.
- Scale up with a scanner and more books once the routine is smooth.
- Remember that income is income. In almost every country profits are taxable, so keep your records in order.
